Burt was looking at a nucleic acid and noticed the following:
it was a double helix, it had the bases thymine, adenine, cytosine, guanine, and it had a 5 carbon sugar. The nucleic acid was...
DNA
RNA
could have been either DNA or RNA
there was not enough information to tell which nucleic acid it was
